Real Dev 测评

Real Dev 是一个我称之为「实战项目的 LeetCode 平台」。跟 LeetCode 相似的地方是,Real Dev 也是一个 OJ (Online Judge);跟 LeetCode 不同的是,Real Dev 不需要大家解决算法难题,但要大家解决工业界常见的实战问题。举个例子,Real Dev 的 Hello World 问题要求大家做一个最简单的 web 服务器,打开 /hello 页面的话服务器要返回 "REAL WORLD"

以下一些是 Real Dev 的问题:自动完成组件(Autocomplete/Typeahead)、短地址生成服务、数据分页 API、响应式配色、JavaScript 到 TypeScript 迁移、克隆 Yelp。这些项目比 LeetCode 的算法题更贴近工业界,更像是软件工程师日常工作需要做的事情。做这些项目时需要用到的技术框架也是工业界所用的:Node.js + Express 或者是 Python + Django。

优点

  • 解题过程更像是软件工程师日常工作。
  • 能够练习使用常见框架,例如 Express 和 Django。
  • 有官方的问题讨论板块

缺点

  • 题目数量不够多。
  • 每道题都要从头开始搭架子。

这次的测评不附送任何折扣链接。Real Dev 是我以前在 Facebook 的同事离开 Facebook 之后做的,他们现在正在做全站打折,由每个月 $20 打折到 $10,这已经是非常便宜的价钱了。大家想要试用的话,直接打开 https://real.dev/ 就可以了,有一部分题目是免费也能访问的。

AlgoTogether 算法学习小组(第二期招生)

我开了一个叫做 AlgoTogether 的算法学习小组,面向在美国寻求软件工程师工作(实习或全职)的人。第一期学习小组的效果不错,学生对项目打分 4.3/5.0 分,对老师打分 4.7/5.0 分(数据),所以我决定开第二期学习小组。针对第一期学生的反馈,我对第二期学习小组进行了调整,最主要的区别是增加了模拟面试的环节。

我知道仅仅通过 LeetCode 准备算法面试是不够的,因为面试并不以题解的优劣来衡量你。你需要让面试官想要和你共事,这需要说服他你能跟他一起通过编程解决难题。AlgoTogether 是一个有教练指导的学习小组,帮助你训练多方面的面试能力,让你在面试时成为面试官的最佳未来同事。在这个学习小组中,你不仅仅需要解题和编码,你还需要练习沟通你的解题思路、接受模拟面试和倾听来自别人的反馈。我们的教练是 ACM/ICPC 奖牌得主,也曾带队其它学生参赛获奖,此外还是大型科技公司中富有经验的面试官。我们保证你投入到面试准备的每一滴汗水都能有充分的回报。

为了保证跟面试和工作环境一致,整个 AlgoTogether 采用全英语沟通。以下是 AlgoTogether 的详细信息及报名链接:

What is this program?

AlgoTogether is an algorithmic problem study group with a coach. The program focuses on all necessary skills for coding interviews: problem-solving, coding, debugging, articulating solutions, taking feedback. The coach leads the meetings and mock interviews and makes sure that students learn these skills in a way that they can reapply to new problems in real interviews.

What is the value of this program?

  1. Understand how an interviewer evaluates you. You are evaluated beyond correctness and optimality. If a company only evaluates these two it will replace human interviewers with LeetCode to save money. You should learn what’s missing beyond your LeetCode practice.
  2. Practice like you are in an interview. You will practice articulating your solution to an interviewer and taking hint or feedback from an interviewer. That’s what you don’t experience if you simply practice with LeetCode.
  3. Hold yourself accountable. Are you willing to commit to finishing a certain amount of problems within a specific time frame? If you can make the commitment, we will hold you accountable and prevent you from slacking.

Who is this program for?

People who are highly committed to getting a software engineer job at one of the well-established tech companies. It’s best for people who are seeking a software engineer job for the first time, for example, newly graduated students. It’s also good for experienced software engineers who haven’t done interview preparation for more than a year.

What is the structure of the program?

The program is 8-week long. Each week the coach picks a theme and assigns problems within this theme. Students have one week to work on them. Then they present their solutions and get mock interviews at the weekend meeting. If they need help they can join the mid-week meeting to discuss. The coach will lead both meetings.

Who is the coach?

Our coach has many years of experience working and interviewing candidates at well-established tech companies. He is also an ACM/ICPC algorithm competition medalist and has coached other students for the competition.

How much does it cost?

$800. We think it’s the right price to identify committed students and hold everybody accountable. You will be able to pay us through a credit card. It’s non-refundable once the payment goes through.
